1 Closing remarks Key qestions: Location of SHE shell and SHE nuclear structure Atomic properties and relativistic effects Breakdown of Mendelejev systematic New approaches Long halflives of transactinides  application of new experimental methods

2 T 1/2 > 10s - Chemistry - Traps Atomic properties Masses

3 Relativistic Extrapolations K.S. Pitzer, J. Chem. Phys. 63, 1032 (1975) V. Pershina et al., Chem. Phys. Lett., 365, 176 (2002) B. Eichler, Kernenergie 10, 307 (1976 ) B. Eichler, PSI Report 03-01, Villigen (2000) Noble gas like Volatile metal

4 T 1/2 > 10s - Chemistry - Traps Atomic properties Masses

5 SHIPTRAP 1 2 Determination of Mass Number (A) Mass Measurements Ionisation potentials (Z) Single-atom chemistry

6 Wien Filter at RIBLL Growing Community Lanzhou GANIL RIKEN

7 Compilation of cross-sections Cold fusion (GSI) based on Pb and Bi targets Hot fusion (JINR) based on actinide targets Surprising high cross-sections (0.5 – 5 pb) for synthesis of spherical SHE 1 pb 1pb: currently 1 atom/ 10 days

8 Upgrade of High Charge State Injector 28 GhZ ion source, new RFQ 50% duty cycle big improvement, but: => e. g. bad use of rare isotopes

9 Project for a superconducting CW-linac U.Ratzinger et al., University of Frankfurt dc beam 1 < A/q < 7 E beam : 4-7.5 MeV/u E beam <  3keV/u Intensity gain: Duty cycle 30%100%3.5 28 (40)GHz ECR-source2-10(?) increased stability (65%  85)% 1.3 shorter shutdowns (107 d/y  47 d/y)1.2 Total gain11-55(?) normal conducting super conducting super conducting

10 Support for theory mandatory, otherwise we will not understand what we are doing

11 GSI colloquium 17 Feb. 2004 Atomic properties: fast chemistry and traps RI beams ???

12 Four major research areas: Nuclei far from stability Hadron spectroscopy ( p ) Compressed nuclear matter Plasma and Atomic Physics existing planned The New GSI Accelerator Facility for Beams of Ions and Antiprotons SHE More visibility needed

13 NUSTAR Nuclear Structure Astrophysics and Reactions Community Council 83 members / institutions Board of Representatives (elected) William Gelletly, Reiner Krücken, José Benlliure, Björn Jonson, Tom Aumann Super-FRS Low Energy Branch High Energy Branch Ring Branch SHE ?
